comprising Donati and BESIX. The contract, worth over 80 million euros, involves doubling State Road 318 over a distance of 3.1 kilometres in the municipality of Valfabbrica, in the province of Perugia (Umbria). This stretch of road includes the Picchiarella and Casa Castalda tunnels, with lengths of 874 metres and 1,545 metres respectively, as well as the Tre Vescovi viaduct and the Calvario bridge.
The project will improve the connection and traffic flow between the cities of Perugia and Ancona. The existing road connecting the two cities will remain in service for the duration of the work.
The construction, organised in seven successive phases, will take 42 months.
The project is the subject of a thorough environmental plan, which will be supervised throughout the duration of the work. The plan includes limiting noise and dust, and reducing earth movements and truck traffic.
The entire infrastructure will be supplied to the client, Anas S.p.A., in the form of a BIM model, facilitating its long-term operation and maintenance.
